Unformatted text preview: shows the change in the form of the force expression when the electrical variable chosen as independent is changed from 2 to i. The result of (3.1.37) can be generalized to a system with any number of terminal pairs in a straightforward manner (see Table 3.1). For a magnetic field system with N electrical terminal pairs and M translational mechanical terminal pairs the conservation of energy equation becomes NM dW, = , i, dij -, fj" dzj. (3.1.38) 1=1 j=1 We now use the generalization of (3.1.31), N N N Zij dA, = Xd(ijA) -A2, di 1 , (3.1.39) =1 j=i1 I t * This manipulation, which represents conservation of energy in terms of new independent variables, is called a Legendre transformation in classical mechanics and thermodynamics. 3.1.2 A-PDF Split DEMO : Purchase from www.A-PDF.com to remove the watermark...
